13 Relationship among the Devices Chapter 1: Advanced Information This illustration shows a cable company that offers DOCSIS- and PacketCable-compliant voice/data services. What the EMTA Does The EMTA provides high-speed Internet access as well as cost-effective, toll-quality telephone voice and fax/modem services over residential, commercial, and education subscribers on public and private networks via an existing CATV infrastructure. It can inter-operate with the PacketCable compliant headend equipment and provide the IP-based voice communications. The IP traffic can transfer between the EMTA and DOCSIS compliant headend equipment. The data security secures upstream and downstream communications. What the EMTA Needs to Do Its Job The Right Cable Company: Make sure your local cable company provides data services that use cable TV industry-standard Euro-DOCSIS or DOCSIS-compliant and Euro-PacketCable or PacketCable-compliant technology. The Internet/Telephony Service Provider (ISP/TSP): Your cable company provides you access to an Internet Service Provider (ISP) and Telephony Service Provider (TSP). The ISP is your EMTA to the Internet and provides you with a pipeline to access Internet content on the 9

14 World Wide Web (WWW). The TSP provides you with telephony access to other modems or other telephony services over the Public Switched Telephone Network (PSTN). Check with your cable company to make sure you have everything you need to begin; they ll know if you need to install special software or re-configure your computer to make your cable internet service work for you. Contact Your Local Cable Company You will need to contact your cable company to establish an Internet account before you can use your EMTA. You should have the following information ready (which you will find on the sticker on the EMTA): The serial number The model number The Cable Modem (CM) Media Access Control (MAC) address The Terminal Adapter (EMTA) MAC address 10

15 Please verify the following with the cable company The cable service to your home supports Euro-DOCSIS or DOCSIS compliant two-way modem access. Your internet account has been set up. (The Media Terminal Adapter will provide data service if the cable account is set up but no telephony service is available.) You have a cable outlet near your PC and it is ready for Cable Modem service. Note: It is important to supply power to the modem at all times. Keeping your modem plugged in will keep it connected to the Internet. This means that it will always be ready whenever you need. Important Information Your cable company should always be consulted before installing a new cable outlet. Do not attempt any rewiring without contacting your cable company first. 11

16 Connecting the EMTA to a Single Computer Chapter 1: Advanced Information This section of the manual explains how to connect your EMTA to Ethernet port on your computer and install the necessary software. Please refer to Figure 1 to help you connect your Digital Cable Modem for the best possible connection. Attaching the Cable TV Wire to the EMTA 1. Locate the Cable TV wire. You may find it one of three ways: a. Connected directly to a TV, a Cable TV converter box, or VCR. The line will be connected to the jack which should be labeled either IN, CABLE IN, CATV, CATV IN, etc. b. Connected to a wall-mounted cable outlet. c. Coming out from under a baseboard heater or other location. See Figure 1 for the wiring example. Notes: For optimum performance, be sure to connect your EMTA to the first point the cable enters your home. The splitter must be rated for at least 1GHz. Fig. 1: Basic Home Wiring 12

17 Ethernet Connection to One Computer Make the connections to the modem in the following sequence: 1. Connect one end of the coaxial cable to the cable connection in the wall, and the other end to the CABLE jack on the EMTA. 2. Connect the plug from the AC power supply into the POWER AC ADAPTER jack on the EMTA, and plug the power supply into an AC outlet. 3. Connect one end of the Ethernet cable (straight-wired, see below) to the Ethernet port on the back of your computer, and the other end to the ETHERNET port on the EMTA. Make sure that the Ethernet cable is straight-wired (not null or crossover-wired). However, you will need a crossover-type cable if you are connecting the modem to a hub, or a hub within a port switch that provides the same function. Note: Use only the power supply that accompanied this unit. Using other adapters may damage the unit. Fig.2: Ethernet Connection 13

18 Connecting More Than Two Computers to the EMTA If you need to connect more than two computers, you ll need the following additional equipment: Crossover-wired, or null, category 5 Ethernet cable for the EMTA to be connected to the hub 10BaseT or 100BaseT Hub or Switch Straight through, or standard, category 5 Ethernet cable (one for each computer to be connected) If you have a hub with an uplink port*, a straight through cable can be used in combination with that port in lieu of the crossover cable. *An uplink port has a small switch on it to change the polarity of the connection. It can accept either a crossover or a straight cable, depending on the setting. Fig.3: Hub Connection Note: You may need to check with your service provider in order to connect multiple computers. 14

19 Telephone or Fax Connection When properly connected, most telephony devices can be used with the EMTA just as with conventional telephone service. To make a normal telephone call, pick up the handset; listen for a dial tone, then dial the desired number. For services such as call waiting, use the hook switch (or FLASH button) to change calls. The following procedures describe some of the possible connection schemes for using telephony devices with the EMTA. 1. Connect a standard phone line cord directly from the phone (fax machine, answering machine, caller ID box, etc.) to one of the LINE jacks on the EMTA. 2. If there is a phone line in your home which is NOT connected to another telephone service provider, connect a standard phone line cord from a jack on this line to one of the LINE jacks of the EMTA. Connect a standard phone line cord directly from the phone (fax machine, answering machine, caller ID box, etc.) to one of the other jacks in the house that uses that line. 3. If you have a multi-line telephone, connect a standard phone line cord (not an RJ-14 type line cord) from the phone to the LINE jacks on the EMTA. (Other phones can be added to each line by using standard phone line splitters. Fig. 4: Phone/Fax Connection 15

20 Activating the EMTA After installing the EMTA and turn it on for the first time (and each time the modem is reconnected to the power), it goes through several steps before it can be used. Each of these steps is represented by a different pattern of flashing lights on the front of the modem. Note: All indicators flash once before the initialization sequence. If all of the lights are flashing sequentially, it means the EMTA is automatically updating its system software. Please wait for the lights to stop flashing. You cannot use your modem during this time. Do not remove the power supply or reset the EMTA during this process. To make sure that you can access the Internet successfully, please check the following first. 1. Make sure the connection (through Ethernet) between the EMTA and your computer is OK. 2. Make sure the TCP/IP protocol is set properly. 3. Subscribe to a Cable Company. Accessing the Internet 4. Once your host PC is properly configured; please proceed as follows: 5.
